SPECIFICATION forming part of Letters Patent No. 788,763, dated May 2, 1905.

Application filed June 23, 1903. Serial No. 162.774.

, Be it known that l, JACOB FELBEL, acitizen of the United States, and a resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-VVriting Machines, ot which the following is a specification.

This invention relates to improvements in the type-actions and carriage-feed mechanism ot' front-strike typewriting machines which comprise pivoted type-bars and meehanism to swing them on their pivots upward and backward to their printing positions, in which they act on the paper on the front ot' the platen, and usually on or near the line on which the horizontal plane that contains the axis of the platen cuts the paper, the object of the invention being to provide such machines with highly efficient type-actions composed ot'simple and easily-assembled parts and having' various peculiar and desirable characteristics, which will be hereinafter explained, and with carriage-feed mechanism titted to be suitably actuated by the type-actions and to coact therewith in accurately controlling' the feed movements of the carriage and in regularly securing a feed movement whenever any type-bar receding from its printing position has traveled a certain distance from the platen.

The invention consists of the various features of construction and combinations and arrangements of parts, all as hereinafter more fully described, and particularly defined in the appended claims.

In the accompanying drawings, in which like reference-numerals designate like parts in different views, Figure l is a central vertical section through the front and back ot the frame of a front-strike type-writing machine with mechanism cmbodyingcertain parts ofthe invention applied thereto and an outline ot' the platen; Fig. 2, a plan ol'l the universal bar ot' the carriage-feed mechanism and horizontal section of levers included in the type-actions; Fig. 3, a front view oi' the universal bar; Fig. it, a fragment ot' the .frame and a clamp attached thereto in perspective; Fig. 5, a Vfront A sectional elevation, on an enlarged scale, ol

Fig. 8, a diagrammatic plan of connectinglinks extending from key-actuated devices like those shown in Fig. l in the front portion of the base to the lower ends of the levers ot' the modiiied system.

The invention is shown applied to a machine all parts ot' which except the type-aetions and carriage-feed mechanism are devoid of material novelty. In the frame of this machine, composed of the base l, posts 2,

'fast on the base, and top plate 3, fast on the 7 5 posts, are tixed guide-blocks It. These guidebloeks are formed on or attached to the sides of the base l and are a little forward of a vertical plane passed in front ot' the platen 5. A

type-barsegment 6 is slidablysecured between 80 justed that the segment is easily movable up S5 and down, but cannot swerve laterally in the guides. The segment 6 contains a series of radial grooves 9, cut in its hollow face, the number o't' these grooves being equal to the number olf type-bars, and within a groove crossing the grooves 9 at right angles and extending' from end to end ot the segment is a curvedv pivot-rod 10. rlhe type-bars l1 are pivoted in the grooves 9 on the rod 10, there beinOa trie-bar in each ot' the grooves 9. 95

l, .l l

On the pivoted end ot' each type-bar is a short arm 12, in which is a hole 13 l'or connection of an actuating-link. lVheu the type-bars A CORPORATLON OF NEV are in their normal positions, they extend forward from the segment 6 and rest near their front ends on a segment 14, which is secured to the segment 6 by bars 15 and provided with a pad 16, of soft material-such, for example, as felt.

Behind the plane containing the rear faces of the guide-blocks 4 and segment 6 are brackets or hangers 17, which are aflxed at their upper ends to the top plate 3 of the frame and connected at their lower ends by a crossbar 18. This cross-bar contains a series of vertical slots 19, extending' through the bar from top to bottom and from its rear face inward a suitable distance, as appears at Fig. 1. A system of levers is mounted on a horizontal rod 20, fixed in this cross-bar and extending from end to end of the bar across the slots 19, there being a lever in each of the slots. The levers are preferably straight, as shown in Figs. 1 and 4. When the system is composed of the straight levers 21, the distance between the hangers 17 is less than the span of the segment 6, and the slots 19 in the cross-bar 18 are so arranged that planes passing through these slots midway between and parallel to their faces cut the holes 13 in the arms 12 of the type-bars. The straight levers 21 extend upward from their pivot-rod 20 behind the arms 12 of the type-bars and are connected therewith by links 22, the Lipper ends of the levers conforming to an arc whose radius is a little shorter than that of the segment 6. The length of the lower arm of each of these levers is equal to that of its upper arm, so the lower ends of the levers also conform to an arc similar to that at their upper ends, and these arcs diverge from each other from the middle to the sides oi' the system.

In the front portion otl the base 1 four parallel cross-rods 23 are secured. These rods are supported at their ends by the sides of the base, each rod being held fast by a clamp at one end or each end of the rod. The construction and operation of one of these clam ps is clearly illustrated at Fig. 4. lt is composed of a block 24, containing a recess 25, in which is a movable jaw 26 on the lower end of a screw 27, the block being affixed to a side of the base 1. The screw fits in a threaded hole in the arm 28 oi' the clamp, and the fixed jaw 29 has in its upper face a groove in which is shown a section of a rod V23, secured between the fixed and movable jaws. The crossrods 23 support key-actuated levers having arms 3() and 31,'which extend backward and upward and backward and downward, respectively, from the cross-rods when the levers are in their normal positions. To the arms 30 of these levers are pivoted the stems 32 of finger-keys 33, and to the arms 31 are attached restoring-springs 34, which are also attached to transverse cross-bars 35, fastened to the base of the Jframe. The stems 32 extend through transverse guideplates 36,

which are fastened at their ends to the frame and which, with the arms 30 of the levers, Y

maintain the stems 32 and finger-keys 33 in their proper positions. The space-bar 37 is mounted on levers on the front cross-rod-23, which are not shown, but which are similar to the levers to which the finger-keys 33 are secured. All the levers on the cross-rods 23 have eyes or bearings 38, and the cross-rods extend through these eyes.

The key-levers described are connected by links 39 with the lower arms of the levers21, these link being secured at their front ends to the arms 31 of the key-levers and extending thence backward to the levers 21 under the type-bars.' Since the system of key-levers is broader than the system of straight sublevers 21, the system of connecting-links 39 is broader at the front than at the rear ends of the links, or, in other words, the links converge slightly from their front to their rear ends, as appears at Fig. 6. With the depression of a finger-key 33 the key-lever connected therewith is actliated, the lower arm 31 of the key-lever being swung toward the Jfront of the machine, so that the link 39, connecting the key-lever with one of the sublevers 21, is drawn forward and the lower arm of the sublever is pulled forward by the link. Meanwhile the upper arm of the sublever pulls the'link 22 backward, and the type-bar is thus swung from its normal to its printing position by the action of the link 22 on the arm 12 of the type-bar. A spring 40, attached to the type-bar and to an arm 41 affixed to the segment 14, helps to restore the type-bar to its normal position. It will be observed that in the operation of this system of type-actions several of the central type-actions of the system are not subjected to any or to any but very slight lateral or twisting strains and that even the other type-actions are not much affected by any such strains, although the links 39 converge from their front to their rear ends, because the inclination of any link to a vertical plane cutting at right angles the axes of the pivot-rod 20 and crossrods 23 is so small and each link 39 is so long that the minute lateral strains exerted on the key-lever and sublever connected by any link absorb but a very small per cent. of the force applied to the nger-key.

The modified system of sublevers shown in Fig. 7 is composed of levers 42, whose ends conform to arcs which diverge from each other from the middle to the sides of the system. The width of this system at the bottom and at and above the pivotal axis of the levers is equal to that of the system of key-levers, and these sublevers are so arranged that the lower end of each sublever is between vertical planes containing the lateral faces of one of the keylevers. In other words, the lower end portion of each sublever is in the same vertical IOO IlO

plane as the arm 31 of the associated key-le- 130 bars.

ver, so that a direct fore-and-aft pull will be exerted from an arm 31 to its associated sublever. These sublevers are connected with. the key-levers by links 43, similar to the links 39; but the links 43 are parallel instead of inclined to a vertical plane cutting at right angles the axes of the pivot-rod 2O and crossrods 23. rlhis modiiied system of sublevers is supported by brackets or hangers 44, a slotted cross-bar 45, and a pivot-rod extending' from end to end of the cross-bar through the slots therein, this pivot-rod .being like the rod 20, except that it is longer. The hangers 44 are similar to the hangers 17, but are farther apart than are the others. They are also affixed to the top plate 3 of the frame, from which they extend downward behind the guide-blocks 4 and brackets 7 of the segment 6. The crossbar 45 is like the cross-bar 18, except that it is longer and that the slots in which the sublevers are secured are farther apart than are the slots in the other bar. The levers of this system, except the two nearest to the middle of it, are bent inward above the cross-bar 45, as shown by Fig. 7, the upper ends of these levers being' in the same positions with relation to the type-bars as are the upper ends of the straight levers 2l of the other system and the radius of the are at the upper ends of the levers 42 being naturally shorter than that of the arc at their lower ends. The upper and lower ends of each lever 42 are equally distant from a horizontal plane containing the axis of the common pivot-rod of the levers. These levers are connected with the type-bars by links 22, pivoted at their rear ends to the upper arms of the levers and at their front ends to the arms l2 of the type- The action of these sublevers will be understood from the foregoing description of that of the sublevers 21. As the lower end of one of them is pulled forward by a link 43 its upper end is carried backward and the type-bar is swung to its printing' position by the link which connects the sublever with the type-bar. Only small lateral or twisting strains are exerted on any of the sublevers of this modified system, although, with the exception of the straight levers at the middle of the system, all are slightly subject to such strains in consequence of the bends in the upper arms of the levers.

The sublevers of each system above described are so arranged that the ends of all the levers swing from side to side of the vertical plane containing' their common axis and are equally distant from that plane when the type-bars are in their normal positions and when they are in their printing positions. The movements of the longest levers, or those at the sides of the system, are consequently measured by the smallest angles, and the move ments of the other levers in order from either of the side levers to the middle levers of the system are measured by progressively-increasing angles, while the ends of every lever are movable through greater distances toward and from the front of the machine than they are toward and from the top of the machine. Since then the ends of each lever move through equal distances er since its arms are subjected to equal strains, it is expedient to make the arms of each straight lever symmetrical, as they are shown in the system illustrated in Figs. l and 5. 1n securing these levers in the cross-bar 18 it is unnecessary, therefore, to exercise care concerning which ends of any lever are made its upper and lower ends, respectively. Moreover, since the lower ends of all the sublevers of either system nieve through substantially equal distances the connections between the sublevers and Finger-keys have movements that are almost equal, and naturally under these conditions the depressions ofthe finger-keys are substantially equal. The arms of each sublever preferably extend from its pivotal axis in diametrically opposite directions, and the sublevers of each system are preferably arranged as described with relation to the vertical plane containing their common pivotal axis; but obviously sublevers differing to a considerable extent in form and arrangement from the levers 21 or 42 might be embodied in lieu of these levers in mechanism containing', essentially, the invention.

Vthe arms of a lever is understood to be a plane containingl said axis and forming right angles with another plane also containing said axis and cutting the arm of the lever at the point where either the power or weight acts on the lever. The ends of a lever are understood to be where the power and weight act on the lever.

The carriage-feed mechanism comprises a universal bar which is operative by the sublevers to regulate the feed movements of the carriage. The bar 46 extends across the frame a little behind and above the common axis of the sublevcrs, being supported at its ends by horizontal guides. These guides are composed of devices 47, afhxed to the base, and of pins 48, fast on the bar and iitting in the devices 47, as appears by Fig. 2, the pins being movable freely back and forth in the eyes of the devices 47. To this bar midway between its ends is attached a rod 49, which extends backward from the bar to and through jan arm 50 on the rock-shaft 5l of a dogrocker 52, there being on the rod 49 a nut 53 to bear against the arm 50 and a lock-nut 54. The dog-rocker carries feed-dogs 55 and 56, which act on the escapement-wheel 56 of the feed mechanism, and on the shaft 51 is a restoring-spring 57. The dog-rocker, arm

50, rod 49, and universal bar 46 are normally IOO Ain Fig. l.

held by the spring 57 in the positions shown That portion of the front edge or face of the universal bar which is directly behind the sublevers and on which they act is composed oi' surfaces 58, intersecting' each other at 59 and there forming an obtuse angle not much smaller than two right angles, as appears by Figs. 2 and 3, the shape of the face being such that it tits against the backs of all the sublevers from side to side of the system when the levers are in their normal positions, whereas it' the face were straight from end to end it would touch only the two side levers. Consequently each sublever acts in the same time on the universal bar and forces it backward when the sublever is actuated by depressing its finger-key. Moreover, the bar is bent at 59, as appears by Fig. 3, so that it makes contact with the sublevers at ditferent distances from the horizontal plane containing their common axis. These distances, which progressively increase from the middle to the sides of the system, are such that the bar is subjected to contact with those portions of the sublevers by which it is movable through a certain distance, so that whatever sublever is actuated the bar is moved to the same extent as it would be if any other sublever were actuated. Obviously it would be movable through a shorter distance by the side levers than it would be by any of the others if it made contact with all thelevers at the same distance from the horizontal plane containing their common axis,'because points -on the side levers have less motion than a point equally distant from the axis on any of the other levers has. The means described for equalizing the movements imparted to the bar by the sublevers would be operative if the bar were not held normally in contact with the levers, so if it were desirable to provide for lost motion between the sublevers and the universal bar that might easily be done by so adjusting the mechanism that there would be a space between the levers and bar when they were in their normal positions; but in this case, as well as in the other, the bar would be movable through a certain distance by whatever lever it might be actuated. Tith the backward movement oi' the universal bar by one of the sublevers the lower end oi' the arm 50 is forced backward, and the dog-rocker carries the yielding dog out of and the fast dog into engagement with the escapement-wheel, and when the sublever returns to its normal position the spring 57 restores the dog-rocker, arm 50, rod 49, and the universal bar to their normal positions, and the carriage is advanced a single letterspace by its driving mechanism. Since the universal bar acts on all the sublevers to the same extent and during equal intervals when it is restored to its normal position by the spring 57, it is easy to so adjust the connection between the dog-rocker and universal bar as to regularly secure a feed movement of the carriage whenever any type-bar hastraveled a certain distance from the platen.

Various changes may be made in the mechanism above described without avoiding the spirit of the invention.
